Effect of fungicides on growth and sporulation of fungal pathogens causing fruit rot of chilli.

A study was undertaken to determine the efficacy of different fungicides in controlling the postharvest fruit rot of chillies (Capsicum annuum) under in vitro conditions. Eight fungicides (0.05% thiophanate-methyl, 0.10% carbendazim, 0.25% mancozeb, 0.20% captan, 0.25% copper oxychloride, 0.20% ziram, 0.20% chlorothalonil, 0.05% triadimefon) were tested using poisoned food technique. Isolation carried out from the disease chilli fruits collected from vegetable market, in Rahuri, Maharashtra, India, over a period of 4 months, yielded Fusarium oxysporum, F. moniliforme [Gibberella fujikuroi], Aureobasidium pullulans and Aspergillus niger. Carbendazim and copper oxychloride completely inhibited growth and sporulation of F. oxysporum, followed by thiophanate methyl. Carbendazim and thiram completely inhibited the growth and sporulation of F. moniliforme, whereas triadimefon was found ineffective. Mancozeb completely inhibited the growth of Aurebasidium pullulans, followed by copper oxychloride and captan, whereas triadimefon, thiophanate methyl and carbendazim were found ineffective. Carbendazim gave the highest per cent inhibition of Aspergillus niger, followed by captan, triadimefon and thiophanate methyl, whereas the least inhibition was obtained in copper oxychloride, ziram and chlorothalonil.
